DescriptionThese devices are monolithic timing circuits capable of producing accurate time delays or oscillation. Inthe time delaymode of operation, the timed interval is controlled by a single external resistor and capacit or network. In the astable mode of operation, the frequency and duty cy cle may be independently controlled wi th two external resistors and a si ngle external capacitor.

Features*Timing from Microseconds to Hours*Astable or Monostable Operation*Adjustable Duty Cycle*TTL - Compatible Output Can Sink or Source Up to 200 mA*Temperature Stability of 0.005% per oC*Direct Replacement for Signetics NE555 Timer
